High Alumina Bricks

High alumina brick is a kind of neutral refractory material,which is made of bauxite or other raw materials with high alumina content. It has high refractoriness,high load refractoriness, good thermal shock resistance,slag erosion resistance, and spalling resistance. Good and other excellent properties are mainly used for heating furnace linings in various steel, chemical, cement and other industries.RS High Alumina Refractory Bricks sells a wide range of high quality alumina bricks with different alumina contents.

High Alumina Brick Description 

High-alumina bricks are hot-selling refractory bricks sold by RS factory, and the main chemical composition is Al2O3.Ordinary high-alumina bricks are alumina siliceous refractory products with an alumina content of more than 48% made from raw materials with high alumina content such as alumina bauxite,which are mechanically formed and calcined at high temperature.When it comes to high alumina bricks with different Al2O3 content there are three types of high alumina bricks sold by RS Group:

I.It is a 75-grade alumina refractory brick with an Al2O3 content of more than 75%.

II.It is a 70-grade alumina refractory brick, and the Al2O3 content is about 60~75%.

III.It is grade 60 alumina refractory brick, and the content of Al2O3 is about 48~60%.In addition to the above high alumina bricks,there is also a corundum brick with an Al2O3 content of more than 90%. RS Refractories Manufacturer can supply all above alumina bricks for sale to countries all over the world.In addition,RS Group can customize high alumina bricks and shapes according to customers' special requirements. Welcome to inquire about the price of high alumina bricks!

High Alumina Bricks Composition

The composition of high alumina bricks determines that it has the characteristics of high load refractoriness and low creep.The main raw materials are special bauxite,corundum, fused mullite and so on.

High alumina brick performance.

• High refractoriness

• High refractoriness under load

• Good resistance to slag and chemical attack

• Resistant to acids, alkalis and peeling

• Excellent thermal shock resistance

• High temperature and low creep

High alumina brick use

According to the description of Wikipedia,high alumina bricks are high temperature refractory alumina bricks,which are widely used in many industries.First of all, refractory bricks are generally used in steel,chemical, cement and other industries.They are then used as refractory linings for various hot kilns.In addition, these refractory bricks are also used in blast furnaces, hot blast stoves, electric furnaces, ladles, ladles, cement kilns, glass kilns, reverberatory furnaces, rotary kilns, etc.Last but not least, alumina bricks can be used as a kind of furnace bricks,such as heat storage checker bricks in open hearth furnaces,non-return plugs and nozzle bricks in gating systems.
